Stuttgart, Germany, 25 April 2011 | AFP

French Open finalist Samantha Stosur continued her impressive run of form at Stuttgart’s WTA tournament by winning the doubles with German partner Sabine Lisicki on Sunday.

The pair enjoyed a 6-1 7-6 (7-5) win over Germany’s Kristina Barrois and Jasmin Woehr in the final.

In the singles tournament, the 27-year-old Australian knocked out second-seed Vera Zvonareva in the last eight, but lost the semi-final to local favourite Julia Goerges.

Stosur is expected to move up to sixth in the world when the WTA rankings are next released.
